serialise
<programming> To represent an arbitrarily complex data
structure in a location-independent way so that it can be
communicated or stored elsewhere.
For example, an object representing a time, with
attributes for year, month, timezone, etc., could be
serialised as the string "2002-02-24T14:33:52-0800", or an
XML element "<dateobj year='2002' month='02' day='24'
hour='14' minute='33' second='52' timezone='-0800' />", or as
a binary string.
As well as providing an external data representation
(e.g. representing an integer as a string of ASCII
digits) and marshalling components into a single block of
data, a serialisation algorithm needs to follow pointers
to include objects referred to by the initial object. This is
further complicated by the possible presence of cycles in the
object graph.
It should be possible to store the serialised representation
on disk, or transmit it across a network, and then restore it
as an object (graph) that is the same as the original.

serial line
Wires which connect two serial ports carrying serial data
consisting of sequential bits represented by one of two
voltages.
A common electrical specification for the signals on a serial
line is RS-423.

Serial Line Internet Protocol
<communications, protocol> (SLIP) Software allowing the
Internet Protocol (IP), normally used on Ethernet, to be
used over a serial line, e.g. an EIA-232 serial port
connected to a modem. It is defined in RFC 1055.
SLIP modifies a standard Internet datagram by appending a
special SLIP END character to it, which allows datagrams to be
distinguished as separate. SLIP requires a port configuration
of 8 data bits, no parity, and EIA or hardware flow
control. SLIP does not provide error detection, being
reliant on other high-layer protocols for this. Over a
particularly error-prone dial-up link therefore, SLIP on its
own would not be satisfactory.
A SLIP connection needs to have its IP address configuration
set each time before it is established whereas Point-to-Point
Protocol (PPP) can determine it automatically once it has
started.

Serial Peripheral Interface
<communications, hardware> (SPI) A serial interface in which
a master device supplies clock pulses to exchanges data
serially with a slave over two data wires (Master-Slave and
Slave-Master). This term probably originated with Motorola in
about 1979 with their first all-in-one microcontroller.

serial port
<hardware, communications> (Or "com port") A connector on a
computer to which you can attach a serial line connected to
peripherals which communicate using a serial (bit-stream)
protocol. The most common type of serial port is a 25-pin
D-type connector carrying EIA-232 signals. Smaller
connectors (e.g. 9-pin D-type) carrying a subset of EIA-232
are often used on personal computers. The serial port is
usually connected to an integrated circuit called a UART
which handles the conversion between serial and parallel data.
In the days before bit-mapped displays, and today on
multi-user systems, the serial port was used to connect one
or more terminals (teletypewriters or VDUs), printers,
modems and other serial peripherals. Two computers
connected together via their serial ports, possibly via
modems, can communicate using a protocol such as UUCP or
CU or SLIP.

Serial Storage Architecture
(SSA) IBM's proposed ANSI standard for a standard high-speed
interface to disk clusters and arrays. SSA allows
full-duplex packet multiplexed serial data transfers at
rates of 20Mb/sec in each direction.
According to John Taylor, programme manager at IBM's Storage
Division at Havant, SSA will be used in arrays of discs
working with high-end computers ranging from mainframes down
to LAN servers. Taylor said that SSA differs from the IEEE
proposed P1394 serial interface specification in its ability
to offer simultaneous multiplexed transfers from more than one
disk or array. IBM also supports the P1394 standard which
will be used primarily by desktop PCs for multimedia
applications.
SSA has received backing from a number of companies including
connector makers Molex, ITT Cannon and AMP, disk drive makers
Conner and Western Digital and RAID array suppliers like
Dynatech and NCR. IBM expects to see the first SSA products
released at Comdex in Autumn 1994 but it will be 1995 before
the products ship in volume.
Under an agreement signed with ASIC maker and ARM licencee
VLSI Technology, IBM will use ARM-based chips made by VLSI
to implement the SSA interface and VLSI will make these cores
available to third parties as one of its Functional System
Blocks.
